<dd><p>Spectral Co-Clustering algorithm (Dhillon, 2001).</p>
<p>Clusters rows and columns of an array <code class="docutils literal notranslate"><span class="pre">X</span></code> to solve the relaxed
normalized cut of the bipartite graph created from <code class="docutils literal notranslate"><span class="pre">X</span></code> as follows:

<p>The resulting bicluster structure is block-diagonal, since each

<p>The method works on simple estimators as well as on nested objects

parameters of the form <code class="docutils literal notranslate"><span class="pre"><component>__<parameter></span></code> so that it’s
possible to update each component of a nested object.</p>
